Thanks for the reply markeb01. I need to better explain. I am wondering about a hand operated cable that runs from the dash to the carb linkage. It is used to increase the idle when the engine is started during cold weather. My dad has a '61 IH truck. When you start it when the weather is cold, you pull the choke cable a little, pull the throttle a little, then you get out of the truck and let it run until the engine warms up. I have found repop cable with knobs for the 60-63 but only the choke knob for the 64. Did the factory offer the throttle cable as an option in the 1964 trucks? I want to keep my truck as stock appearing as I can. I do not want to drill a hole in my dash to install a cable if it was not a factory option. I have looked at the many factory/stock threads here and have not found anything about it. Sorry that my question was not clear in what I was asking in the 1st attempt.
